The Helmet Diamond Glass 4D is a tempered glass screen protector designed specifically for the iPhone 11 to shield the display from daily wear. Its 9H hardness provides a strong defense against scratches and shocks, while the 4D full coverage ensures that the protection extends smoothly over the curved edges of the screen. To keep your view clear, it features an oleophobic coating that minimizes fingerprints and grease buildup, paired with high transparency to maintain the original vibrancy of your colors. You will notice that the touch sensitivity remains unchanged, as the glass is engineered to preserve the phone's native response. The black frame includes precise cutouts for the front camera and sensors, ensuring no functionality is blocked. This protector arrives securely mounted on a rigid backing within a cardboard box, making it easy to handle during installation.
